CAR-GOUPLING.

SPEGII'I'CATION forming part of Lette m Patent N0. 338,107, dated March16, 1886.

Applieation filed J anuary 9, 1886. Serial N0. 188,131. (N0 model.)

Be it known bhat I, EGBER'I G. SESSIONS, a citizen of the United Stabes,residing als Rice, in the county of Navarro and Sbate of Texas, haveinvented new and useful Improvements in OanOonplings, of which lahefollowing is a speoification.

My invention relates 130 a car-coupling in which the opposite draw-headsare provided Wit;h interlooking projeelsions and connected loy ahorizontal pin or pins.

The invention eonsisbs in the construction and combination of partshereinafter speoified.

In the annexed. drawings, Fignre 1 is a plari view of a car-couplingembodying my invention. Fig. 2 is a horizontal section 0f the same. Fig.3 is a side view of ehe coupling. Fig. 4 is an end elevation of abox-car provided witl1 my improved ooupling atlaachn1ents.

Referring 130 bhe drawings, lshe lebten A designates a draw-head, withextension B anal spring O als its rear end. Eaoh draw-head is provioledab one side With an end projeetion, D, which is reotangnlar in form.This real:- angnlar prdjection D is provided near the bocl y ofthedraw-head with a horizontally-elonganed opening or passage, E, ancl nearits ouiser end said projection has avertieal slot, F, the walls ofsaidslots being ronnded internally, as shown in Fig. 3. 'lhe unter end ofeach draw-head. also carries a wedge shaped projeobion, G, which has ahorizontallyelongatecl sich, E, through its enlarged end, and a verticalslot, F, through its small end, the interior of said slots 01 openingsbeing rounded. The wedgeshaped projection G has a horizontal top andbottom surface. One side is parallel with the side ofohe recbangularprojecbion, and its other side is inolined forward. This wedge-shapedprojection Gis located near oneside ofhe drawhead, opposite 110 and inline with the rectangular pro j ection D, Which is preferably locat-eddirectly on the obher side edgeofthe draw-head. The conpling-pins H Hare passed horizontally through ehe inberlooking projections D and Gfron1 opposite sides of the draw-heads, each pin being engaged in thehorizontal slots E E in the projections of one draw-head, and. in theverbical slots F F in the projeclgions of the opposite draw-head. 111will be observed that the olose engagement 0f each horizontalcoupling-pin ab tw0 point-s in Ehe draw-head 130 whicl1 in is atlsachedseoures a firn1 and steady drafta, while ohe loose or flexibleengagement; of said pins with the opposite draw-heads enables the oars120 tnrn curves readily wilshout liability of derailment. By meansoftl1e vertical slots F F in the encls of the projeetions Band G anup-and-down motion is permibted to the pin H, held in the horizontalslots E E 0f the opposite dr aw head. 'lhis coupling is thereforeadapted to connectz cars having draw-heads of differenb height-s, aswell as those that are arranged on a level. Bach coupling-pin H isoarriecl at the lower e11d 0f a vertical rod, K, that is pivoted ab L110 the end of a freight-car 01' to a convenienb point on the platformof a passengencar. In order 130 hold the rod 01 lever K in any desiredposition, raoks m m are provided, Wibh which said rod 01 leve1 can beengaged. Thisrod or lever K may extend to the top of a freight-oar andthe raoks m be locabed upon the top 0f the car, as shown in Fig. 4:.

II: will be seen thal: Witl1 tl1is constrnction and arrangernent ofdefices cars of the same or difierenl; heights can be easil y and quicll y coupled and unconpled eitaher from the top or platal'orm 0f a car,or fron1 either'side, wibhout any risk of injnry to the abtendant.

Whal: I olaim as my invention is The eombinalsion, with Ehe draw-headsprovided with projeclzions D and G, each having ab its inrier porlaion ahorizontally-elongatecl slot, and ab it s outer portion averLically-elongated slob, of l;he horizontally-slidable coupling-pins HH, f0r respecbively engaging the said slobs, substantially asdesoribecl.

In testixnony whereof Iaffix 1ny signature in presence of two witnesses.
